Titan (T16) Viewed by Cassini's Radar - July 22, 2006


Published


This radar image shows the entire scene in which hydrocarbon lakes were first discovered on Titan, near its north pole (see <a href="http://photojournal.jpl.nasa.gov/catalog/PIA08630">PIA08630</a>). This image was acquired on July 22, 2006, by Cassini's radar instrument in synthetic aperture mode. The most striking landforms are the lakes: dark patches, some circular, some irregular, many with apparently steep rims, over much of the terrain north of 70 degrees latitude. The most convincing lake forms occur at the narrowest, central part of the scene, which is at the highest latitudes. Here they have short, stubby channels leading into them, and brighter areas within that indicate either dried-up lakes or that we are seeing through a transparent liquid. The image also shows the considerable variation in the kinds of surface features found at different latitudes. Beginning at the left (20 degrees north by 142 degrees west) and heading north, a circular feature about 75 kilometers (47 miles) in diameter is seen, which could be either an impact crater or a volcanic caldera. Other less distinct circular forms are seen next, possibly including some dried lakes, followed by some ridge-like terrain with dark meandering channels or valleys. The dark lakes begin to appear next (at about 70 degrees north), with more distinct lakes in the middle of the scene, where the swath is closest to the pole and starts to descend to the south. Farther on, apparently dry lakes and canyons begin to dominate, and the region becomes more complex and etched. At the extreme right end, dunes similar to those seen previously mingle with brighter features. The swath ends at 13 degrees north by 347 degrees west. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The radar instrument was built by JPL and the Italian Space Agency, working with team members from the United States and several European countries.
